Hanuman, a great devotee of Sri Ram, is the symbol of devotion and dedication. Hanuman carried Sri Ram and Lakshmana on his shoulder when they were in search of Sugreeva, the king of Vanarav in Kishkindha and helped them to find Sita.
Prior to the war between Sri Ram and Ravana, Anjaneya visited Lanka, met Ravana, created havoc and burnt down the city of Lanka (Lanka Dahan). During the war, when Lakshmana was injured seriously, Sushena, the surgeon/physician of the monkey army, despatched Maruti to bring herbal medicine, Jadi Buti, from the far-off Sanjeevini mountain in the Himalayas, before sunrise. Flying over the Himalayas and unable to identify the particular herb fast, Hanuman uprooted and carried the entire Sanjivini mountain in time to save the life of Lakshmana. Hanuman was blessed by Sri Ram with immortality (chiranjeevi).
Hanuman was a bachelor and is worshipped in all the temples of India. Every temple of Sri Ram contains an icon of Hanuman.
